- Scattered showers (30-60%) early this morning over northern WI. 15-30% chance of a brief shower early this afternoon mainly in Door County.
- Next chance of a few showers (20-40%) over central WI late Monday night. Shower and storm chances Tuesday into Wednesday have decreased.
- Scattered rain chances return on Friday, but the rain this week will do little to put dent into growing drought conditions over the area.
